Well today was time to start working on the vent lines in the fuselage. I've always known that I wanted to do something a little fancier than the "cut a bulkhead fitting at 45 degrees", so here's a picture story of what I ended up with.
Starting materials:
Thinning out the nut:
Turn down the diameter:
Hack out a little "airfoil" from the chunk of aluminum:
Notch the two parts...
...and press them together:
Trim off the requisite 45 degree angle:
A pass with the buffing wheel and this is whatcha get:
...and
that, my friends, is how you blow a day doing a five minute job.
